A well preserved specimen 46mm. long and 22·5mm. wide (Fig.17) was found by Mr. R. Cory near Catadupa. The body whorl is contracted below the suture and has ten varices which die away at the anterior contraction and are slightly acute at the shoulder; the anterior part of the shell has five wavy spiral ridges. A smaller and more delicate but poorly preserved form (Fig. 18), with similar but more anteriorly produced varices, occurs just above the Barrettia limestone at St. Ann's Great River and resembles specimens of L. crassicostata Stol. from Assam figured by Spengler (Pal. Ind., N. Series, vol. viii, mem. i, 1923, pl. iii, figs. 34a, and b). Another species of Lyria or Volutilites (Fig. 16) with elongated spire has about 7 coarse uneven varices on the body whorl and occurs as badly preserved casts in the Providence shales. It attains a length of 47 mm.

In the course of a voyage across the Pacific in September, 1924, from Vancouver to New Zealand, I broke my journey at Suva for four weeks with the object of seeing something of the geology and scenery of Viti Levu. Half that time, however, was spent in a cruise to the Tonga Islands and Samoa, leaving therefore only a fortnight for Viti Levu, but His Excellency the Acting Governor, the Hon. T. E. Fell, C.M.G., gave me facilities for visiting the mountainous country of the interior which enabled much more of the island to be seen in that short time than would otherwise have been possible. To him and to other officers of the Government who assisted me in my tour I offer my best thanks. Mr. F. R. Charlton, the Acting Crown Surveyor, accompanied me on my coastwise journey and in a traverse across the island from north to south. His knowledge of the country and of the Fijian language and customs was invaluable. Major Caldwell, Mr. Reay, and Mr. Armstrong, the District Commissioners through whose areas we padded, gave us hospitality and every assistance possible, and Mr. Boyd, the Commissioner for Native Affairs, made arrangements with Fijian chiefs, in whose houses we were charmingly and hospitably entertained. When making the tour I had no intention of writing any account of it for publication, but several new facts came to light which it is desirable to place on record.

The genus Promicroceras was separated from Xipheroceras by Dr. L. F. Spath to include Ammonites capricornoides and the Am. planicosta group. The researches of Dr. W. D. Lang on the Dorset coast have shown that the genus Promicroceras persists with relatively slight changes from the “birchi” zone up to the “ziphus” zone.

1. The Dent Fault diminishes in throw towards the north, and is almost non-existent 3 miles south of Kirkby Stephen.

2. The principal line of dislocation is then displaced about a mile to the east, where there is a steep monoclinal fold, replaced sometimes by a fault, running in a direction parallel to the Dent Fault and also having a downthrow to the east.

3. Further parallel faults, many of them hitherto unmapped, assist in the subsidence of the country to the east.

4. Cross-faults, in most cases with downthrow to the south, accommodate the margin of the “Rigid Block” to local increase or decrease of throw.

5. These two systems of faults are of approximately the same age, and were brought about by the same crustal movements.
